Abstract:- Concrete is absolutely indispensable in modern society’s fascination with new roads, buildings and other constructions. It is estimated that the present consumption of concrete in the world is of the order of 10 billion tonnes (12 billion tons) every year. The structural concrete elements can be formed into a variety of shapes and sizes. This is because freshly made concrete is of a plastic consistency, which permits the material to flow into prefabricated formwork. After a number of hours, the formwork can be removed for reuse when the concrete has solidified and hardened to a strong mass. The present research explores the possibilities of geopolymer concrete for economy and environmental sustainability. The results of present study revealed that Heat-cured fly ash-based geopolymer concrete using foundry sand offers several economic benefits over Portland cement concrete. The price of one ton of fly ash is only a small fraction of the price of one ton production of Portland cement. Keywords: Geopolymer Concrete, Fly Ash. 1. Introduction The fly ash is used instead of cement along with alkaline liquid to produce geopolymer concrete (figure 1). Fly ash and alkaline solution is used to make binder which binds the coarse & fine aggregate. It’s a new technology that reduces carbon dioxide emission to the atmosphere [25]. Inspired by this new technology an attempt has been made to develop an alternative concrete binder or a substitute for cement by using the geopolymer technology and utilizing the fly ash as main ingredient to produce geopolymer concrete. Geopolymer concrete is designed same as cement, concrete design methods.
Figure 1 process of making geopolymer concrete. Fly ash was used in small proportions in mass concreting for dams and other hydraulic. Fly ash closely resembles volcanic ashes. It was used in production of the earliest known hydraulic cement about 2,300 years ago. Instead of volcanoes, today's fly ash comes primarily from coal-fired electricity generating power plants. These power plants grind coal to powder fineness before it is burned. Fly ash – the mineral residue produced by burning coal - is captured from the power plant's exhaust gases and collected for use. 2. Objectives of the Study The objectives of this study are: 1.
To utilize the waste material such as foundry sand, fly ash in geopolymer concrete.
